+==== Just Executable

+- `just_executable()` - Absolute path to the just executable.
+
+For example:
+
+```make
+executable:
+    @echo The executable is at: {{just_executable()}}
+```
+
+```
+$ just
+The executable is at: /bin/just
+```
+
 ==== Dotenv Integration
 
 `just` will load environment variables from a file named `.env`. This file can be located in the same directory as your justfile or in a parent directory. These variables are environment variables, not `just` variables, and so must be accessed using `$VARIABLE_NAME` in recipes and backticks.
